Let's divide 51191329 by 191
We want to figure out the number of times 51191329 can be divided by 191.

On to step 1:
191 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 191

Let's proceed to step 2:
191 goes into 51 0 times with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (1) of the dividend behind the 51 and repeat the process: 511 / 191

Moving on to step 3:
If we divide 511 by 191, we get 2 and a remainder of 129.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 382 from 511, we get 129.
Take the next digit (9) from the dividend and append it to 129, then repeat: 1299 / 191

Step 4:
191 goes into 1299 6 times with a remainder of 153.
The next digit of our result is 6. 
Result so far: 26.0
If we subtract 1146 from 1299, we get 153.
Grab the next digit (1) from the dividend, add it to 153, then carry on: 1531 / 191

Going ahead to step 5:
The number 191 fits into 1531 8 times, leaving a remainder of 3.
The next digit of our result is 8. 
Result so far: 268.0
Subtract 1528 from 1531 to get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 191

Moving on to step 6:
33 divided by 191 is 0 with a remainder of 33.
The next digit of our result is 0. 
Result so far: 2680.0
Subtract 0 from 33 to get 33.
Bring next digit (2) of the dividend behind the 33 and repeat the process: 332 / 191

Moving on to step 7:
If we divide 332 by 191, we get 1 and a remainder of 141.
Record the quotient 1 as the next digit in the result. 
Result so far: 26801.0
Subtract 191 from 332 to get 141.
Take the next digit (9) from the dividend and append it to 141, then repeat: 1419 / 191

On to step 8:
The number 191 fits into 1419 7 times, leaving a remainder of 82.
Record the quotient 7 as the next digit in the result. 
Result so far: 268017.0
Deduct 1337 from 1419 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
If we divide 820 by 191, we get 4 and a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 268017.4
Subtract 764 from 820 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
If we divide 560 by 191, we get 2 and a remainder of 178.
The number 2 becomes the next digit in our result. 
Result so far: 268017.42
The remainder is 178 after subtracting 382 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 11:
191 can be fit into 1780 9 times, resulting in a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 268017.429
Subtract 1719 from 1780 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 12:
If we divide 610 by 191, we get 3 and a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 268017.4293
The remainder is 37 after subtracting 573 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 13:
370 divided by 191 is 1 with a remainder of 179.
Use 1 as the next digit of our solution. 
Result so far: 268017.42931
If we take 191 away from 370, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Step 14:
When dividing 1790 by 191, we get 9 with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 268017.429319
Subtract 1719 from 1790 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 15:
191 can be fit into 710 3 times, resulting in a remainder of 137.
Use 3 as the next digit of our solution. 
Result so far: 268017.4293193
Subtracting 573 from 710 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

On to step 16:
If we divide 1370 by 191, we get 7 and a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 268017.42931937
Subtracting 1337 from 1370 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 268017.42931937, with a leftover of 3.3e-08.
